The invention relates to a (coiler rfor eliot rod mills and more GSPGOIally tOCOi lBI mechanism for hot'rod mills and merchant inn-ills, or

y othersimilar purposes. i '5 The primary object of theinvention is the provision of mechanism ofthischaracter for use inconnection with wire :rod rolling :mills and for similar purposes, wherein reeling or coiling means is operative so that the coil receptacles are disposed with relation to .each other whereby one-ofthesame will be i-na receiving position and the :other a discharg ing position and in this manner the co'i ls will be produced and discharged on the reversing of said means during the continued operation thereof and the coils discharged can be delivered onto atab'le or conveyor directly from the mechanism.

Another object of the invention isthe provision of mechanism-of this character wherein several reels or coil receptacles are arranged movable or revol-uhle about a center or axis and-adapted to be alternately brought into position for-respectively receiving a coil of rod and then tilted or inverted for eifecting the discharge automatically of the coil therefrom and this operation being continuous during the working of the mechanism.

A further object of the "invention is the wherein the reels or ceiling receptacles, each is adapted to be inverted from receiving position and when inth-is position will :act upon the coil to reduce the spread thereof and finally discharge the said coil-onto a-depositor such as a table or conveyor, the mechanism being of novel construction and is automatic in operation for the continuous receiving and discharging purposes for the coiling of wire rods successively and the delivery thereof as a product A still further the provision of mechanism of this character wherein coilers are operative for coiling hot bars or rods rolled on a merchant inill or rod mill and the coiling being automatically effected and a deposit of the coil after being made for the delivery thereof, the coiling and the delivery being automatic :and the operaf h ni in of this character provlslon O meg a S the'l1ne of Figure 2look1ng 1n the diobject of the invention is 1931.

-A still further object of the invention is the provision of mechanism of this character.

whrchis comparatively simple in construe --t-i'on,' thoroughly reliable and efficient in -:op-

eration, compact in thewagrou pment .of its parts, readily :and easily operated, and inexpensive toimannfacture and install.

With these and :other objects in view, the

invention consists in the features of construction, combination and arrangement of parts aswvill beherei-nafte'r more fully described in detail, illustrated in the acconr panyin-g drawings, which disclose the pre lferred embbdilnent :of' the invention, and polsnted eat the :c'laims hereunto appended.

Figure 3 is. an enlarged sectional view on rection of 'theiar-rows. a

Figure 4 is a fragmentary sectional view-0n the line 4+4 of Figure 1.; a

Similar reference characters indicate corresponding parts throughout the several views in the draw Referring to :the drawings in detail, there is shown .a pair of spaced vertical bearing stands 10, the upper ends of which are formed with bearings 11 in which are journalled trnnnions 12 formed on a turning body 13 at opposite sides thereof and this body is preferably of cylindrical formation in cross section to provide a housing having circular recesses or pockets 14 in opposite ends and opening therethrough, while centrally of these recesses or pockets 14 are aligned columns 15 which constitute bearings for a pair of opposed rotatable stud shafts 16. These 'ing or body an open center 21 in the housing or body 13 and fixed to the inner end of said shaft is a beveled pinion 22, the latter meshing with crown gears 23, these respectively being secured to the inner ends of the stud shafts 16 so that the receptacles 17 will be driven in unison.

The other trunnion is provided with an oil duct 24 which is closed at its outer end by a removable plu 25 and this duct permits the introductionof oil to the gears and pinions within the hollow center 21 of the hous- 13 for lubricating purposes. Arranged diametrically opposite on the housing or body 13 in suitable bearings 26 thereon and externally of the same are turning shafts 27 ,these being equidistanced apart and extend slightly beyond the ends of the housingor body 13. Upon opposite ends of each shaft 27 are furcated heads 28 in which are pivoted at 29 tilting members 30 each being formed with an axle 31 carrying a roller 32 designed to overhang the receptacle 17 adjacent thereto and contact at certain times with the rim 19 thereof, while the other end of the member 30 carries an adjustable weight 33 which overbalances the roller 32 for a purpose presently described. 7

The shafts 27 carry pinions 34 which mesh with toothed sectors 35 on a sectional shiftable ring or wheel 36 loosely embracing the housing or body 13 and supported for shifting movement thereon.

The shifting of the ring or roller 36 throughthe medium of the sectors 35 meshing with the pinions 34 will cause the swinging of the members 30 from the posit-ion shown by full lines in Figure l of the drawings to the position shown by dotted lines in said Figure 1 or to swing ninety degrees for a purpose presently described.

The shaft 20 which is the power shaft for the coiler receptacle may be driven either from a suitable motor or coupled direct with a wire rod rolling mill, while the trunnion 12 receivingsaid shaft *20is equipped'with a worm gear 37 which latter may be driven from a suitable motor or other power me- I dium for a turning of the body or housing 13 to continuously'reverse the positions of the coiler receptacle 17 therein contained from receivin to discharging position.

In the operation of the coil ng mechanism a hot wire rod is introduced into the recep- 7 tacle 17 uppermost in the body or housing period, the rollers ing or operative positionby the-ring or wheel a) 13 and in this manner under the rotation of said receptacle the coil will be formed, whence the said body or housing 13 will have traveled by turning movement to invert the aforesaid receptacle to a discharging position or lowermost of sald body or receptacle coil 38 will be regulated or the coil thinned. 30

For the discharge of the coil 38 from the lowermost receptacle 17 the ring or'wheel 36 will have been moved to'shift the rollers 32 by reason of the engagement of the sectors 35 with the saidrollers will be outwardly out of the path of said receptacle 17 and thus release the coil 38 for the discharge of the same onto a table or conveyor atthe option of the user of the mechanism. This operation is con 90 tmuous and the receptacles 17 both in receiving anddischarging positions are driven from a single power shaft 20 through the pinion 22 and gears 23meshing with each other.

When the receptacle 17 has been moved from'lowermost to uppermostposition, which latter is the receiving position the rollers 32 by the action of the weights 33 will rock on the pivots 29 to have the arms disposed at a lateral outwardly directed angle and thus not interfere with or impede the-introduction of thewire rod into the coiler receptacle 17 forv the coiling thereof at the introductory 32 being thrown to work- 36 through the sectors 35 meshing with the pinion 34 on the shaft 27, the ring or wheel 36 beingautomatically tripped or' shifted in any desirable manner.

of a receptacle 17 will be positively driven for reducing the spread of the coil operated upon by the rollers 32 and the thinning of such coil immediately prior to the discharge of the coilfrom the mechanism.

It is of course to be understood that changes, variations and modifications may be made in the mechanism without departing from the spirit of the invention or sacrificing 7 any of its advantages and as fall within the 15 scope of the appended claims.

From the foregoing it is believed that the construction and manner of operation of the mechanism Will be clearly understood and therefore a more been omitted.
